Oh I don't know, shorter exposure, maybe a white balance adjustment or some post color balance. Depends on what you were shooting for. Want to see an edit?
BTW - I was going to say something harsh, but my since of humor is already borderline. :mrgreen:
Ok, just for fun here are some tweaks, including a parallax adjustment and some color balance. No right VS wrong, just something to look at.
Oh, and take a bath!
Its a great shot nonetheless but its not original. Everyone that goes to the grand central sets there camera on the banister and takes a long exposure.
I really like the shot though, i like how the ceiling looks in it. (if that makes any sense)
Hang around until just before closing time when the place is nearly empty, and the guards are playing catch with the sniffer dogs on the slick tiles.
